Upgrading freeradius from source

[mctiew at yahoo.com]

I have done some testing on 2.1.4 and I like the flexibility
comparing to 1.x.

Unfortunately, I am using for production a pretty old distribution
1.1.7. For such an old distro, it's almost impossible to do an 
upgrade and still maintaining the rpm package info and what not, 
so I am considering upgrading by compiling from source, ie
configure and make install.

Any thing I should consider before I have go down to this path ?

Cheers.
